(6) HOLDOFF ControlWhen observing signals containing pulses at differentintervals in spite of constant repetition of pulses, im-proper adjustment of the H O L D O F F control (§) resultsin doubled waveform display. In such a c a s e , adjust theH O L D O F F to obtain stable triggering.I n p u t s i g n a l< H O L D O F F ( a )H O L D O F F ( J ;If the HOLDOFF is set like a , waveforms © and @ aredisplayed on the C R T alternately.D o u b l e d w a v e f o r m d i s p l a y d u e t o i m p r o p e rH O L D O F F a d j u s t m e n tBy adjusting the H O L D O F F to condition b , waveform© only is displayed on the C R T .[2] SWEEP MAGNIFICATIONW h e n observing a part of waveform by expanding the timea x i s , quickening the s w e e p time may exclude the part tobe observed from the C R T . The sweep magnification is usedin s u c h a c a s e for proper observation. Move a part to beobserved to the C R T center with the «*3 • P O S I T I O N con-trol knob (§). Pressing then the x 10 M A G s w i t c h © turnson the L E D and magnifies the part tenfold. T h e s w e e p timeof the readout values displayed on the C R T is decupled.N O T E : S w e e p magnification is impossible if A INT B or X - Yof the H O R I Z O N T A L MODE s w i t c h e s is selected.[3] DELAYED SWEEPThe A sweep and B sweep are used for delayed sweep mag-nification.1 . Continuous Delay (Start After Delay)The continuous delayed s w e e p can activate delayeds w e e p operation from any point of A s w e e p .a) Select of the H O R I Z O N T A L M O D E s w i t c h e s © andset each control and switch for normal waveform ob-servation.b) Select A INT B of the HORIZONTAL MODE switches© and set the B S O U R C E to A F T . D . A brightintensity-modulated part is displayed on the A sweeptrace. Its intensity can be controlled with the P U L LB INTEN @ . Length of the intensity-modulated partto be magnified depends on setting of the B S W E E PT I M E / D I V control (magnification ratio). Move theintensity-modulation part to a part to be magnifiedwith the D E L A Y POSITION @ . T h e delay time is dis-played in the upper right of the C R T .c) By setting the HORIZONTAL MODE switches to A L T ,t w o trace lines of the A s w e e p and B s w e e p are dis-played alternately, enabling magnified and non-magnified parts to be observed simultaneously. Iftrace lines of the A s w e e p and B s w e e p are hard tobe observed due to overlapping, control the T R A C ES E P © to shift the B s w e e p w a v e f o r m to an easy-to-see position.Fig. 1824F i g . 1 4O n - C R T, d i s p l a y © ,O n - C R T, d i s p l a y ©O n - C R T, d i s p l a y ©O n - C R T, d i s p l a y ©Fig. 17Fig. 1 5H O L D O F F i s p r o p e r l y a d j u s t e dFig. 16M a g n i f i e d i n t e n s i t y - m o d u l a t i o n p a r tA s w e e pt r a c e lineB s w e e pt r a c e line
